My zune won't turn on

No probley not it needs a new battery more than likely they can be bought for around $25.00 or so no fun to put in very delicate.

Hold the power button for 10 seconds. this should cause reset. if it does not hold it again for 15 seconds this should cause it to power into repair mode where you will then need to plug it into your computer and update the firmware with the included software. hope this helps!

Press up and the back button at the same time for about ten seconds. This should reset your zune.

Mine was completely drained of battery, and wouldnt turn on, just leave it plugged into your computer for 20 minutes and see if it atleast give the low battery warning.

More than likely the battery just needs to be replaced. I let my nano go dead and it was doing the same thing. So just get it replaced and that should fix your problem.

There's a fix:

Your zune will need a "hard reset."

To do this, use a small screwdriver to pop off the plastic shielding where the zune cable plugs into and remove the two screws on either side of the plug. Next pop the cover off and locate the battery plug at the top left corner of the zune, using your screw driver, pop the cable connection half way off, and do this to the other plug on the right side. Wait 3 seconds, then push down the right connector and then the left battery connecter. Your zune should start up immediately. Press the backing of the zune down (make sure headphone jack is aligned) and put the screws and cover back in place.

It's an easy process but if you're unsure don't attempt it.

To reset the zune you must press and hold the back button and the top part of the zune pad. Other parts of the zune pad will not work.

When plugging the zune into your PC does the PC detect it (device manager -> portable devices). You should hear the ding sound of hardware connecting.

If it is connecting to the PC and is not detected by the software than it is likely a permissions problem. Right click the software icon and choose run as administrator.

If it is not detected by the PC than check your usb cable and make sure your zune is charged and not frozen.

Download and install the latest zune software from microsoft. Run the new zune software, plug your zune into the computer and it should prompt you to install the latest firmware automatically. This is all that is necessary with the majority of firmware problems.

my son's just did this and the reset method worked (press the back button and up and hold both for about 10 seconds until the zune screen appears)
